Simple Power up down Sequencer Circuit Diagram
Power-up/down Sequencer Circuit Diagram. Whether you’re talking about a home cinema or a computer system, it’s very often the case that the various elements of the system have to be turned on or off in a quite specific order, or at least, automatically. Constructing this sort of automation system is well within the capability of any electronics enthusiast worthy of the name, but in this ‘all-digital’ age, most of the circuits of this type to be found in amateur electronics magazines or web-sites use a microcontroller. Even though that is indeed a logical solution (in more ways than one!), and you might even say the easiest one, it does pose problems for all those people who don’t (yet) have the facilities for programming these types of IC. So we decided to offer you now an approach that’s very different, as it only uses a simple, cheap, commonly...
